UNLOADING APPARATUS.

Application filed July 5. 1919.

To all whom it may concern.

Be it known that 1, WILLIAM CRILLY, a citizen of the United States,residin at Chicago, in the county of Cook and tate of Illinois, haveinvented certain new and useful Improvements in Unloading Apparatus, ofwhich the following is a specification.

This invention relates to improvements in unloading apparatus,particularly adapted, though not necessarily limited in its use, forunloading open cars, and one of the objects of the invention is toprovide an improved, simple, compact, portable and self-containedapparatus of this character which is adapted to he placed upon the carand moved lengthwise and crosswise thereof to any position with respectto the car so as to remove all of the contents of the car and deliverthe same outside of the car. 7

To the attainment of these ends and the accomplishment of other new anduseful objects as will appear, the invention consists in the features ofnovelty in substantially the construction, combination and arrangementof the several parts hereinafter more fully described and claimed andshown in the accompanying drawings, illustrating this invention and inwhich; V

Figure 1 is a side elevation of the apparatus showing the same inposition upon a car.

Fig. 2 is an end elevation of the apparatus.

Referring more particularly to the drawings, the numeral 10 designatesthe ordinary car body particularly adapted for carrying coal and similarmaterials. The apparatus is adapted to be placed upon the top of theside walls of the car and to travel upon the angle irons 11 usuallyprovided in cars of this character. If, however, it is found that theupper edges of the walls are irregular, then the rails 12 may beemployed for sup porting the apparatus and as tracks for the apparatusto run upon. These tracks maybe held in position in any suitable mannersuch as by means of posts 13 adapted to extend downwardly on the insideof the car.

The apparatus consists primarily of a main supporting frame having sidebars 14L and end bars 15 and which frame is supported by means ofsuitable wheels 16 adapted to engage and run upon the tracks 12 when thetracks are employed or upon the angle irons 11 of the car. Projectingupwardly from one side of the main supporting frame and adjacent eachend thereof, are

Serial No. 308,699.

A supplemental frame is provided to move 7 with the main supportingframe and with respect thereto and in adirection transverse to thedirection of movement of the main supporting frame; This supplementalframe may be of any desired configuration, but preferably comprises abottom 24 having uprights 25 at one edge and an inclined up wardlyprojecting portion 26 at the other edge of the bottom and projectingabove the upper edge of the inclined portion 26 are uprights 27 andwhich uprights 27 are connected with the uprights 25 by means of crossbars 28. The uprights 27 preferably project for a short distance abovethe cross bars 28 as at 29 and this upwardly projecting portion isreinforced by means of braces Mounted upon the upright 17 of the mainframe, is a bar or track 31 preferably of channel iron construction.When the two frames are assembled, the uprights 1729 will stand adjacenteach other so that wheels 32 which are connected with the supplementalframe preferably by means of the uprights 29, will engage and run uponthe bars or channel irons 31 which serve as a track for the wheels.Additional wheels 33 are connected with the supplemental frame on theopposite side thereof and adjacent one of the cross bars 14 which latterforms a track upon which the wheels 33 rest and travel.

It will thus be seen that as the main frame is moved in one directionacross the car, the supplemental frame will be carried thereby and thissupplemental frame, inasmuch as the tracks or supporting rails l i-31are arranged transverse to the tracks or rails 12, will be adapted for amovement across the car in a direction transverse to the movement of themain supporting frame thereacr oss. This independent movement of thesupplemental frame may be accomplished in an suitable manner such forinstance as by means of a hand wheel 34 connected with the shaft 85,having a worm 36 thereon which meshes wit-h a worm gear carried by theaxle of one of the wheels Mounted upon the supplemental frame,preferably upon the bottom 24, is a conveyer of any suitable style butpreferably a screw conveyer 37 which operates within a trough 38 and thetrough is of a length to extend entirely across the car in adirectiontransverse to the direction of movement of the main supporting frame,This conveyer may be of any desired length but preferably is of a lengthto extend beyond the side of the car and is provided with a deliverychute 39 for delivering the material therefrom. The free end of theconveyer is supported in any suitable manner such as by means of a cable40 connected at one end as at 41 to the free end of the conveyer and isconnected by means of an anchor 42 to a fixed support on thesupplemental frame.

Pivotally mounted by one end and upon the supplemental frame is an armor boom 43 which may be of any desired length and carried by the freeend of this arm or boom is a sprocket wheel 44, while a similar sprocketwheel 45 is located at the other end of the boom adjacent its pivot. Anendless flexible element or belt 46 passes over these sprocket wheelsand scoops or buckets 47 are connected with the endless element. Withthis construction, it will be noted that there is only a single endlesselement to which the scoops or buckets are secured and this element islocated preferably centrally of the buckets so as to be protected by thebuckets or scoops These buckets are pro vided with closed bottoms andeach of the buckets is so constructed that it will overlap the nextadjacent bucket thereby forming a continuous support for the material inthe scoops or buckets which will prevent the material from droppingthrough the buckets and interfering with the endless element 46.

The sprocket wheel 44 is preferably mounted in an adjustable bearing 48adapted to be adjusted by means of a suitable adjusting screw 49 so asto take up the slack of the endless element '46. WVith this constructionit will be manifest that the boom like elevator is pivotally supportedby its upper end so that its lower end will have a free swinging pivotalmovement, thereby adapting the free end of the elevator to be positionedso as to engage the material in the car. hen the car is full and theapparatus is first started to be used, the boom like elevator willassume the position shown in dotted lines in Fig. 1, that is with itsfree end resting on the top of the material. As the elevator isoperated, the free end of the ele-' vator, as the material is removed,will gravitaie as indicated diagrammatically'in dotted lines in Fig. 1toward the bottom of the car until it assumes'the position shown in fulllines in Fig. 1. As the material is then re moved from the'car, with thefree end of the elevator depending below the support and into the car,the main supporting frame may be advanced or the supplemental frameadvanced with respect to the main supporting frame so as to position theelevator to remove all of the contents of the car.

Motion may be imparted to the elevator to operate the scoops or buckets47 in any suitable manner such as by means of a motor 50, preferablymounted upon the supplemental frame, and which motor is connect ed inany suitable manner such as by means. of a chain orvbelt 51 passing oversuitable sprocket or pulley wheels 52-52. Theconveyer 37 also receivesits motion from the motor 50 by means of suitable connections such as abelt or chain 52 passing over asuitable pulley or sprocket connectedwith the conveyer and also over a suitable sprocket wheel or pulley 54connected with the sprocket 45.

In order to provide for the proper speed and to reduce the speed of themotor 50 to adapt it for operating the elevator and conveyer, a suitablereducer 55 maybe provided which is connected with the shaft 56 of themotor through a suitable coupling 57.

The free end of the elevator may be swung about its pivotal support inany desired or suitable manner, preferably by means of cables 58connected with the free end thereof, and which cables vpass oversuitable pulleys 59 mounted in suitable bracketsor I earings 60 on thesupplemental frame and over drums 61 also mounted upon the sup plementalframe. These drums 61 may be rotated in any suitable manner such as bymeans of a crank '62 through intermediate gear connections 63 and thefree end of the elevator may be supported and maintained in its adjustedposition by means of a suit-- apparatus of the character describedadapted to rest and travel upon the top of the walls of a car, saidapparatus embodying a conveyer for receiving and delivering the contentsof the car outside thereof, an elevator for delivering the material tothe conveyer, means for moving the elevator and conveyer lengthwise ofthe car, means for ,ed to be supported by andto travel upon the top ofthe walls of a car, said apparatus" embodying a main supportingframe.'movable in one direction back and forth across the car, asupplemental frame 'mount'ed upon the main frame for movement therewithand with respect thereto across the car in a direction transverse to thedirection of movement of the main frame, an elevator pivotally supportedat one end by the supplemental frame whereby its free end will have afree swinging movement about the pivot, and a conveyer positionedadjacent the pivoted end of the elevator to receive the material fromthe elevator at any point of adjustment of the elevator and deliver thematerial outside of the car.
